What Fideres does

Fideres is a London-headquartered, litigation-only economic consulting firm founded in 2009 by Alberto Thomas (former Head of Structured Products at RBS, ABN AMRO, and UBS) and Steffen Hennig, both fixed-income veterans who built the practice in the wake of the financial crisis. The firm provides economic expert analysis and testimony exclusively for plaintiffs and litigation funders across the full lifecycle of a case — early case evaluation, novel theories of harm, damages modeling, class certification, expert testimony, and settlement. Its structural differentiator is conflict freedom: Fideres does no merger advisory and operates without walled-off teams, so it is fully available for plaintiff-side engagements in matters where conflicted consultancies cannot act.

The service portfolio spans six practice areas — antitrust, securities, financial, consumer protection, discrimination, and environmental litigation — delivered through proprietary damages modeling methodologies, quantitative market analyses, and a network of 30+ affiliated academic experts from institutions including MIT, Stanford, Oxford, and Cambridge. Fideres operates from five primary offices (New York, London, Frankfurt, Madrid, Rome) plus Johannesburg, serving law firms and litigation funds across more than 10 jurisdictions. Revenue is generated through professional services fees negotiated per engagement; pricing is not publicly disclosed. Track-record matters include a USD $2bn settlement in the Credit Default Swaps Antitrust Litigation (Quinn Emanuel), the first certified UK consumer class action against Amazon Buybox affecting 50+ million consumers (Hagens Berman), a €6.5bn Steinhoff accounting fraud recovery (Burford Capital), and a £1bn+ Microsoft Azure consumer class action (Scott+Scott). The firm is privately held as Fideres Partners LLP, with no external institutional investment evidenced.
